Quasi steady-state hurricanes revisited

open access: yesTropical Cyclone Research and Review, 2019
We revisit the theoretical possibility of long-term, sustained tropical cyclone solutions using a state-of-the-art numerical model that incorporates the most recent observational guidance for subgrid scale parameters and airsea exchange coefficients of ...

Improved Spoofing Loosely Coupled INS /GPS with ‎Steady State Kalman Matrix Gain [PDF]

open access: yesفصلنامه علوم و فناوری فضایی, 2023
This paper presents a solution for detecting and recovery for the spoof error of GPS receiver signals, in order to increase the accuracy of the navigation system integrating inertial systems with GPS signals.

A steady-state thermoreflectance method to measure thermal conductivity.

open access: yesReview of Scientific Instruments, 2019
We demonstrate a steady-state thermoreflectance-based optical pump-probe technique to measure the thermal conductivity of materials using a continuous wave laser heat source. The technique works in principle by inducing a steady-state temperature rise in

On Exact and Approximate Approaches for Stochastic Receptor-Ligand Competition Dynamics—An Ecological Perspective

open access: yesMathematics, 2020
Cellular receptors on the cell membrane can bind ligand molecules in the extra-cellular medium to form ligand-bound monomers. These interactions ultimately determine the fate of a cell through the resulting intra-cellular signalling cascades.

Fundamental Relation for the Ideal Gas in the Gravitational Field and Heat Flow

open access: yesEntropy, 2023
We formulate the first law of global thermodynamics for stationary states of the ideal gas in the gravitational field subjected to heat flow. We map the non-uniform system (described by profiles of the density and temperature) onto the uniform one and ...

Entropy Generation in 2D Lid-Driven Porous Container with the Presence of Obstacles of Different Shapes and under the Influences of Buoyancy and Lorentz Forces

open access: yesNanomaterials, 2022
This paper includes a numerical investigation of a hybrid fluid containing 4% of Al2O3-Cu nanoparticles in a lid-driven container. The upper wall of the container has a high temperature and is movable. The lower wall is cool and wavy.

Three Unique Interstitial Macrophages in the Murine Lung at Steady State

open access: yesAmerican Journal of Respiratory Cell and Molecular Biology, 2017
&NA; The current paradigm in macrophage biology is that some tissues mainly contain macrophages from embryonic origin, such as microglia in the brain, whereas other tissues contain postnatal‐derived macrophages, such as the gut.

A Review of Fusion and Tokamak Research Towards Steady-State Operation: A JAEA Contribution

open access: yesEnergies, 2010
Providing a historical overview of 50 years of fusion research, a review of the fundamentals and concepts of fusion and research efforts towards the implementation of a steady state tokamak reactor is presented.

Detrending the Waveforms of Steady-State Vowels

open access: yesEntropy, 2020
Steady-state vowels are vowels that are uttered with a momentarily fixed vocal tract configuration and with steady vibration of the vocal folds. In this steady-state, the vowel waveform appears as a quasi-periodic string of elementary units called pitch ...

Embryonic and adult-derived resident cardiac macrophages are maintained through distinct mechanisms at steady state and during inflammation.

open access: yesImmunity, 2014
Cardiac macrophages are crucial for tissue repair after cardiac injury but are not well characterized. Here we identify four populations of cardiac macrophages.
